CRF 28
Higher CRF = smaller file, lower quality. Output: H.264 MP4 + AAC audio. Dimensions and frame order are preserved; odd dimensions receive a one-pixel pad. Comparison uses matching decoded frame numbers, not independently playing videos.

How it works
The single-thread FFmpeg engine downloads when you compress your first video. Your video stays on this device. Keep this tab open while encoding. Browser memory and speed vary; use short clips. Compression may increase the size of an already optimized video. FFmpeg and its core are open source; dependency licenses and source are included in the build.
